Hi y'all, Just bought an MSI P67a-GD53 (B3) Motherboard to replace a faulty ASUS board and the damn thing won't even POST.... Specs as follows Intel Core i5 2500k 2 x 2GB Corsair XMS3 1600Mhz RAM MSI Twin Frozr GTX560Ti Antec Trupower 650W Modular Power Supply Crucial RealSSD 64GB Thermaltake Fri CPU Cooler The problem I'm having is the system won't POST at all. When I plug in and power up all the fans (CPU,System & GPU) spin up, all the CPU Phase LEDs light up and remain lit but the monitor displays "No Signal" and there are no beeps from the internal speaker. I have tried with both sticks of RAM in the primary slot (the blue one closest to the cpu) and I've tried booting with CPU only, CPU + RAM only, CPU + RAM + GPU only.... all giving me exactly the same problem. All power cords are correctly connected, I've tried breadboarding the whole thing to ensure there are no short circuits. The only time it does anything different is when i leave the 8-PIN CPU power connector unplugged, in which case only the first CPU phase LED lights up and all the fans spin up for approx 4 secs before powering down, then powering back on again and repeating until I cut the power. Any bright ideas on what could be wrong before I RMA the board?
